Given numbers are 397, 621, 504, 245

The list of prime factors of all numbers are

Prime factors of 397 are 397

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 504 are 2 x 2 x 2 x 3 x 3 x 7

Prime factors of 245 are 5 x 7 x 7

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 397, 621, 504, 245

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(397, 621) = 246537

GCD(397, 621) = ( 397 x 621 ) / 246537

= 397 / 621

= 397

Step2:

LCM(1, 504) = 504

GCD(1, 504) = ( 1 x 504 ) / 504

= 1 / 504

= 1

Step3:

LCM(1, 245) = 245

GCD(1, 245) = ( 1 x 245 ) / 245

= 1 / 245

= 1

So, Greatest Common Divisor of 397, 621, 504, 245 is 1
